A home equity loan is secured debt. Your house is the collateral: when you sign the loan, you also sign a mortgage or deed of trust that gives the lender a legal claim against your property, and that claim gets recorded in the county land records. If you stop paying, the lender can foreclose and sell the home to recover what it’s owed. That single fact, the collateral behind the promise to repay, is what separates a home equity loan from unsecured products like credit cards and personal loans, and it drives almost everything else about how the loan works.
What “Secured by Your Home” Means
Secured debt is debt tied to a specific asset the lender can take if you default. Unsecured debt isn’t. A credit card issuer that doesn’t get paid can send your account to collections and sue for a money judgment, but it can’t point to a particular thing you own and seize it. A home equity lender can. The mortgage or deed of trust you sign at closing creates a security interest in the property, and once that document is recorded, the debt and the house are legally linked until the loan is paid off or the lien is released.
The size of the loan reflects the value of that collateral. Most lenders cap home equity loans at a combined loan-to-value ratio of 80% to 85%, minus what you still owe on your first mortgage. Some stretch to 90%. On a home appraised at $400,000 with a $250,000 first-mortgage balance, an 80% CLTV leaves room for a home equity loan of up to $70,000.
Why Secured Status Gets You a Lower Rate
The clearest benefit of pledging collateral is cheaper interest. As of early 2026, average home equity loan rates hover around 8%, well below the 20%+ typical on credit cards and the 10% to 15% range common on unsecured personal loans. Lenders price to the risk they carry, and the risk is smaller when a house stands behind the loan. If the borrower defaults, the lender has a legal path to recover.
The trade is direct. You’re paying less in interest because you’ve handed the lender the right to take your home if things go wrong. For a borrower who can comfortably afford the payment, that’s a good deal. For a borrower who is stretching, it swaps a cheaper monthly cost for a much heavier consequence of default.
The Core Risk: Foreclosure
Because a home equity loan is secured by your residence, default can cost you the residence. Foreclosure is the mechanism. The lender enforces its recorded lien, forces a sale, and applies the proceeds to the debt. A home equity lender can start this process even if you’re current on your first mortgage. Junior lenders foreclose less often in practice, because they’d need to deal with the senior mortgage to protect their position, but the legal right is there.
Default isn’t only missed payments. Home equity loan agreements typically also treat unpaid property taxes, lapsed homeowner’s insurance, or serious deterioration of the property as triggers. Any of these can put a superior claim on the house or erode the collateral, and lenders write the contract to protect against that.
If the foreclosure sale doesn’t bring in enough to cover what you owe, the lender may pursue a deficiency judgment for the shortfall, subject to state law. That risk is sharpest for home equity lenders in second position: if the first mortgage swallows most of the sale proceeds, the home equity lender recovers little from the property and may come after you personally for the rest.
Where a Home Equity Loan Sits in Line
A home equity loan is almost always a second mortgage. Lien priority follows a recording rule: whichever lien was recorded first in the land records has the senior claim. Your original mortgage lender recorded first, so it holds the senior lien. The home equity lender recorded later and holds a junior lien.
That order controls who gets paid when the property sells. The senior lienholder is paid in full before any proceeds reach the junior. If a home sells for $300,000 and the first mortgage balance is $280,000, only $20,000 is left for the home equity lender. When the sale doesn’t even cover the first mortgage, the home equity lender gets nothing from the sale itself. This is also why home equity loan rates run slightly higher than first-mortgage rates on comparable balances: the junior lender is taking on more risk of loss.
Lien position becomes a practical problem if you later want to refinance your first mortgage. Once the original first mortgage is paid off and released, the home equity loan automatically moves up to first position. A new refinance lender won’t accept second position and will ask the home equity lender to sign a subordination agreement pushing its lien back down behind the new first mortgage. Home equity lenders aren’t required to agree, and some refuse or charge for it. Worth checking early rather than at closing.
The Trap of Consolidating Credit Cards Into a Home Equity Loan
One of the most common reasons people take out a home equity loan is to pay off credit card balances. The math is appealing: swap 22% interest for 8% interest. The math usually works. What changes underneath the math is the nature of the debt.
Paying off a credit card with a home equity loan converts unsecured debt into secured debt. Before, the worst outcome of not paying was a lawsuit, a judgment, and possibly wage garnishment. After, the lender holding what used to be credit card debt can foreclose on your house. If the consolidation is part of an actual restructuring of your finances, the lower rate is real savings. If it frees up credit lines you’ll run back up, you now have a home equity loan secured by your house and fresh unsecured balances on top of it. That’s a worse position, not a better one.
Tax Treatment Depends on How You Use the Money
Because the loan is secured by your home, the interest can be deductible, but only under specific conditions. Interest on a home equity loan is deductible on your federal return only if you used the proceeds to buy, build, or substantially improve the home that secures the loan. Use the money for anything else, including paying off credit cards or a vacation, and the interest is not deductible.
The overall cap for deductible mortgage interest is $750,000 in acquisition debt for married couples filing jointly, or $375,000 filing separately, on loans taken out after December 15, 2017. That cap covers your first mortgage and home equity loan combined. If your first mortgage balance is already $700,000, only $50,000 of home equity debt fits under the cap.
A substantial improvement, in IRS terms, is work that adds to the home’s value, extends its useful life, or adapts it to a new use. A kitchen remodel, a new roof, or an added bedroom qualify. Routine maintenance like repainting doesn’t on its own, though it can count when it’s part of a larger qualifying renovation. Keep invoices, contracts, and receipts that tie the loan proceeds to specific improvements; that’s what holds up if the IRS questions the deduction.
The deduction only helps if you itemize. For 2026, the standard deduction is $32,200 for married couples filing jointly, $16,100 for single filers, and $24,150 for heads of household. Unless your mortgage interest plus other itemized deductions clears those numbers, the deduction is worth nothing in practice.
HELOCs Are Secured Too
A home equity line of credit is also secured by your home, so the collateral analysis above applies equally. The difference is only in how you use the money. A home equity loan gives you a lump sum at closing with a set repayment schedule. A HELOC gives you a credit line you draw from during a draw period, usually at a variable rate, with payments that move as your balance and the rate change. Both are second mortgages, both put the house on the line, and both carry the same foreclosure risk, lien priority rules, and tax treatment.1Consumer Financial Protection Bureau. What Is the Difference Between a Home Equity Loan and a Home Equity Line of Credit
The choice between secured and unsecured borrowing isn’t really a choice about interest rates. It’s a choice about what you’re willing to put behind the loan. A home equity loan is the cheaper option because your house is the answer to the question of what happens if you can’t pay.
